Another good location for scenery is any city park. Understand that you will have a certain "Gawk" factor, as people have a curiosity when they see non-ten year olds "playing" with toys. But the parks can provide some background scenery and locations for shots. You can also work the Industrial angle using home built cityscapes married and/or overlaid with real city shots. This tends to require a bit of Photoshop work. Just look around. There is scenery everywhere, just use your imagination.
